Magnetic classification - ScienceDirect

Jan 01, 2002  Magnetic separation is recognised as a commercialy effective method for the recovery of minerals since the beginning of the last century. Constant development of new machines presenting better performance has been witnessed (Augusto, 2001c), and nowadays we may surely say that the separation of magnetic particles presents high accuracy (Augusto and Martins, 2001).

Magnetic Separation - an overview ScienceDirect Topics

Magnetic separation takes advantage of the fact that magnetite is strongly magnetic (ferromagnetic), hematite is weakly magnetic (paramagnetic), and most gangue minerals are not magnetic (diamagnetic). A simple magnetic separation circuit can be seen in Figure 1.2.5 [9].A slurry passes by a magnetized drum; the magnetic material sticks to the drum, while the nonmagnetic slurry keeps flowing.

Magnetic separation - Wikipedia

Magnetic separation techniques are also used in microbiology. In this case, binding molecules and antibodies are used in order to isolate specific viable organisms, nucleic acids, or antigens. This technology helps isolating bacterial species to identify and give diagnostics of genes targeting certain organisms. When magnetic separation techniques are combined with PCR (polymerase chain reaction), the results increase in sensitivity and specificity.
